Yes, It is important to know the volume of Unknown acid or base to be titrated.
Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.
M₁V₁/n₁ = M₂V₂/n₂
Answer:
Polar
Explanation:
There are more electrons at the oxygen, and nitrogen oxides have an electronegativity that leads to a polar bond due to this uneven valence electron formation.
Answer:
The correct option is: a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy
Explanation:
Respiration refers to the catabolic reactions in the cells that produce energy in the form of adenosine triphosphate (ATP) from various nutrients.
An aerobic respiration, is a spontaneous process that involves the use of <u>molecular oxygen (O₂) to produce energy (ATP). In this process, molecular oxygen oxidizes nutrients such as carbohydrates, fats, and proteins; to give carbon dioxide, water and heat energy</u>.
Answer:
faster because atoms move faster when heated . If the temperature of the salt is extremely hot, a thin layer of vapor will form on the surface, insulating the salt from the water.
Explanation:
Na is the symbol for sodium.
